Why?

How?

What?

Our nation's homes use more than 20 percent of energy produced and account for about as much greenhouse gas emission.
There are more than 100 million existing homes in the United States, many of which are in dire need of significant improvements.
Between 1978 and 2005, energy use per household dropped by more than 30 percent.
That's good, but it's not good enough. The United States consumes more energy than any other country in the world. Changing our homes is the first step in a brighter energy future.

By improving the tools and resources available to professionals and consumers so that they can retrofit houses to improve energy performance.
